INTERIOR EIECTRIC-LIGHTING SYSTEM.

Specification of Letters Patent.

Original application filed September. 9, 1904, Serial No. 223,899. Dividedand this application flied September 27, 1911.

To all whom it may. concern:

Be it known that I, ANnR BLoNonL, a citizen of the Republic of' France, residing -at'Paris',France, have invented certain new and useful Im rovements in Interior Electrio-Lighting ystems, of which the followin is a specification.

y invention relates to improvements in interior electric lighting systems by flaming or luminous arc lamps, wherebyvsuch lamps are adapted for the lighting of rooms, halls,

'and other inclosed spaces, without subjecting the occupants of the room or other space to the inconvenience and danger of the poisonous products of combustion and with- I out disfigurement or soiling of the walls of the room, or of the furniture, by the depo-'.

I forms apart of this specification, Figure 1 is avertical section through the casing andglobe of an arc lamp. adapted to my-improved system, Fig. 2 is an elevation of the system itself, the ceiling of the room or space in which it is installed being in section. a I

Like numerals indicate like parts in the drawing.

vMy invention provides means -for'carrying theproducts of combustion from ally the lamps which arejinstalled in a room, hall,

off-other space, either outside the, room or' to somedefinite. place inside the. room, to a depositing and'purifying chamber common to all the l'amps, and. fromthere' the air, cleaned of its noxious rodu'cts of combustion, bacl'r through the amps.

Referring to the drawing; a for use in .my system-is shown 1n out ine, There is a housing 1 for the regulating mechanism, the-tubes fl 2 descending-fromthe same'and connected atthe' lower ends by-a cross'pi'ece 3, anuPperielctfode-A, and

a lower' electrode 5, both. guided in their movements by the tubes 2 but the regu lamp ada ted 4 Serial No. 851,491.

part of my invention, and any suitable regulating mechanism may be used. The upper electrode passes through an economizer- 6, as is usual withflaming arc lamps, and this economizer is set in a diaphragm 7, which is secured to an annular chamber 8. A'sec- 0nd diaphragm 9, parallel to and below-the diaphragm 7, issecured to the loweredge of the annular chamber 8, and the guide tubes 1 22 pass through both diaphragms. 'The lower diaphragm 9 hasa wide central opening through which'theflaring funnelportion of the economizerflprojects, and this. opening is wide enough. to permit the products of combustion from the arc to freely ascend into the chamber'S. A glass globe 10 has its upper edge provided with a metal facing 11, which fits closely overlthe lower edge of the annular chamber 8, and the globe is held in place in that position by hooks 12, ,or other like devices, in such a manner that it may be removed when required for trimming the lamp, as is usual. The lower end of the globe is provided witha short tube or nipple 13,- indicated in Fig.

to the canalization as will presently appear.

" The canalization is composed of two lines of pipe, one line '17- extending along the region of lamp distribution and near the ceiling 18 of the room or hall in which the lamps are installed, and the otherline 19 also extends along the region of the. lamp distribution close, to the. lower ends ofthe lamps. The nipples 13 are connected withthis lower line of pipe 19, whilethenipples 16 are connected wi 'theupper line of p1 17-. Either within the room inwhich e adapted "22, connected at one end to the bottom of line of through 9, into the annular 1 products of combustion and 'ca'nalization.

, understood that Arrows in hall s, workshops, etc, the persons inihese spaces "to the "effect of lamps are installed, at some suitable out of-t 0-way place, or outside the room to belighted, t ere is installed a purifying and depositing chamber 20, made of any glood conductor of heat, such as metal, w ic in this instance is shown as secured to the ceiling, but which may be otherwise disposed. In this chamber there are filtering layers 21, suitably separated, and above these or between them, or both, are placed chemicals to absorb or neutralize the non. solidifiable and oisonous products of combustion coming om the lamps. The filters and the whole body of the chamber operate to condense upon-their surfaces the so1idifiahle products of combustion. Below this purifying and condensing chamber is installed a suitably driven air pump or fan the .urlfym and condensin chamber-by a pipe 23 and at' the other en d to thelower line of pipe 19,. as indicated. The upper" ipe 17 is tapped into the upper of t e purifying and condensing chainas shown.

Any number of.- lamps may be connected to the canalizationin the-manner indicated in Fig. 2, in-w'hich, by way of example, threesuch lamps are shown, and it to be beyond the last of these' lamps the pipes 17 19 are closed. in any de-' sired mannerand by any desired means;
